WEBSTER M. ROBERTS, OF ST. JOSEPH, MISSOURI.

To auw/1.0m# may concern.

lic, it kno'vn that I, lVi-:lis'rnu M. Rom-urls, a citizen of the United States, residing at St. Joseph, inthe county of Buchanan and State of Missouri, have invented certain new and useful 'Improvements in Baking and Molding Devices, of which the following is a specification( reference being had therein to the accompanying dran-'ing This invention relates to a molding device for producing improved pastry products, the use 0f the molding device including a novel process of manufacture.

The use of the invention produces an im- .proved pastry article adapted to be filled with food or confcctions and having a hard 'impervious surface whereby cream or the like will not penetrate the article.

An object is to produce an improved molding device, whereby such articles may be molded and then baked, the improvement consisting mainly in the provision of a mold lined with nickel or nickel plated.

The use of such a mold results in a novel processof moldingand baking pastry articles, the employment of a nickel lined or nickel plated mold, doing away with the necessity of usingr as much grease in the .molds as was previously required.

Among the advantages to be derived from the use of such nickel lined or nickel plated molds in the baking of batter products, as above referred to, are that much less grease is necessary, an actual saving of some two gallons in a twenty-four hour run being accomplished, andthe further great. advantage that suchI a m'old may be used on a new inachine without having to go through a preliminary operation of greasing the molds until they become grease tempered. Also, in the use of such molds no cleaning of them is necessary as the pastry or batter products do not stick to the molds and this prevention of need for cleaning prevents delay in the operation of the molding devices and prevents the spoilingof such articles as formerly stuck to the mold and were therefore destroyed.

The result referred to is produced by the employment of nickel lined or nickel plated molds apparently for the reason that. nickel is a. very close grained metal and therefore it does not allow the grease to be absorbed in its, surface as does cast. iron. Also, the factthat the nickel is smooth and does not cause. sticking of the batter articles provides BAKING AND MOLDING DEVICE.

y Specification of Letters Patent. Patented Feb 18, 1919. Application med August 20. 1917. Y

Serial No. 187,043`

a machine in which there is less strain on the parts due to theseparation of the mold elements and it also provides a batter product having an impervious surface and asmootll polished exterior. The surface of the article is such that. the material with which it is illcd in practice, as ice cream for examplc.. does not entcrthc surface of a baked article.

The drawings are to be understood as merely illustrative and as showing some of the uses to which a nickel lined or nickel plated mold may be put.

Figure l is a vertical section of a mold particularly adapted for baking the ordinary ice cream cones of commerce, the mold being shown as sectional and as provided with an inner memberconstituting a. core;

Ifig. 2 shows a mold adapted to form pastry shells. such as patties to contain vegetables or the like, this ligure showing a mold having a single outer member and an intelrior core. i

It will be understood that the types of molds lshown are simply illustrative and that they would in practice be used in an organized machine of some type. For example, the mold of Fig. 1 may be employed in the machine of the patent to Roberts, No. 1,147.974. granted to the present applicant and lark D. Robertson July 27th. 1915. Ilowcver, the present invention may be employed in many other relations.

Referring to 4the drawings, Fig. l shows a mold having sectional outer members l and which may be provided with corrugations 3. The. core. t is constructed to shape the batter and form a cone of the shape of the core. In use the two outer mold sections I l and 2 are connected together and then the hattcr is poured in any desired way into the batter cup thusl formed. Insertion of the core 2% into thc mold sections 1 'and 2 serves to force the batter up the inner edges of these sections and thus form the material into the desired cone shape. The entire mold is then carried or movcd in any desired wa v into a heating oven or heat-ing furnace. and the batter then baked.

l't will be noted that the mold sections 'l and l and the core l are cach provided with nickel lined surfaces 5. These may be actual thin sheets of nickel or theI nickel may be plated onto the material` such as cast iron, forming the mold sections and the core.. In most. cases the nickel would be applied by a baked batter product. 4Here also there is a sheet or plate of nickel 8 von the outer moldsection 6 and on the core 7 The operation of the device of Fig. 2 is l substantially like that of Fig. 1 except as to the closing of the mold sections and need not be further described. A

The applicant has found that the use of nickel lined molds and cores in such relations as are'herein pointed out is of great advantage. When inordinary household use a new dgriddle is to be employed'it must be grease very thoroughly until the griddle becomes what is called grease tempered and an additional amount of grease continued to be used until that tempering eHect is produced. The pores of the iron must absorbi and retain enough grease so that the cakes do not stick before it becomes a satisfactory utensil. This situation is precisely what occurs in the baking of such Abatter products with ordinary cast iron molds. When a new machine is produced it is necessary to use grease very profusely for some time. The grease in practice is painted on with a brush and that operation continued until the machine turns out perfect cones or pastry shells. This may require several days and yconsumev much valuable material without the production of commercially usable articles.

If the molds are nickel lined or nickel plated it is possible to start a new machine and within thirty to forty minutes be producing perfect cones or other articles. .Thus, the delay in placing a new machine in operation is obviated, together with the very considerable loss of spoiled material in producing the grease tempering before referred to.

Also, in'the continued use of such machines when cast iron molds are' used the grease gradually `works into the iron until it forms a coating. This becomes sticky and partv of the cones adhere to the iron, causing much breakage of the product. It 1s then necessary to shut the machine down and give it a thorough cleaning, requiring several days labor and considerable material. The highly burnished nickel lining being practically without pores keeps the grease from entering into the metal and thus does not require the periodical cleaning of the machine. Also, due to the surface not becoming sticky the lcones continue to come out of the machine easily without causing the extra strain found in machines employing cast iron molds. In fact, the strain is so y ployrnen't` of the' nickel" Lacasse great in the case of ca stjiron molds it'frc-A quently causes breakage-of the molds and this is entirely done awayf'ywit n 'i'nickel plat- 111g. L

Also, in actual use the-nickel plate permits the use of considerably lessv'grease. ..It Vhas been found by actual test that in an organized machine a saving "of: two gallons of the shortening oil used which provides the greasing effect was obtained in a twenty-four hour run of the machine. Furthermore, the pastry articles, `such as ice cream cones, produced from such nickel plated molds havea highk polish and a hard impervious surface which does not take up the contained article, `such, as ice cream, readily. The articles also have a smooth polished exterior which produces a better appearance than similar articles formed with a cast iron mold and the articles produced f Y by nickel plated molds are therefore more salable and a better commercial product.

-It will be understood that in the drawings the nickel lining it shown with muchl eX- aggerated thickness for clearness. The nickel may be very thin, and if the nickel is plated on the mold electrically, its thicki.. ss may be onlvfa few hundredths of an inch, or some such small amount.

' Anovel method of baking batter products is disclosed in this application but is not claimed herein.

Having thus fully described my invention, what I claim as new .and desire to secure by Letters Patent, is

1. In a baking apparatus, a baking mold.

having an interior surface lined-with nickel.

2. lIn a baking apparatus, a bakinff mold having an interior nickel plated surface.

3. In a baking apparatus, a baking mold having a corrugated interior surface lined with nickel.

4. In a baking apparatus, a baking mold having a corrugated interior nickel plated surface.

5.`In a baking apparatus, a baking moldV ner mold member having a nickel plated ex-` terior and coperatinp' with said outer member to form a cupped batter product.

In testimony whereof I affix my signature.
